The bands are further riveted to an upper and,I lower track4 designed to give: greater strength to the connection. The troughs, the Vgusset plate,andthe steel band are further secured' to one another lby counterfsunl; holes having their peripheral edges compressed one into 1theother and-,held by rivetsl in the holes. Thel connecting bolts andthe receiving apertures therefor have been tapered to facilitate the insertion thereof. The track carrying therollers operating the conveyor have been provided with integralflanges; it will be appreciated. that by this structure deposition of .material on thebearing surface isprecluded.

In the event of the kconveyer being installed on uneven surfaces, theprovision of bands having,inclinedupturnedends hasbeen made to permit relative vertical movement there- This con struction allows the bandsto be drawn tightly together, although the adjacent troughs do not lie in the same horizontal plane. Y

-With theseand other objects in view which may be incidentto my improvements, the invention consists in theparts and combinat-ions to be hereinafterset forth andl claimed, i with the understanding that-the several neces-l sary elements comprising my invention, may be varied in construction, proportions and arrangement, without Ldeparting from the spirit andscope of the appended claims.

1 In order to make my invention more clearlyV understood, I have-shown inthe accompany? ing drawings means for 'carryingithesame proveme'ntsin their usefulV applications to the particular constructions, which for the purpose of explanation, have been made the sub-A ject-ofillustration. Y

Referring bynumerals to the drawings, in Figures 1 and 2 adjacent conveyerv trough unitsare designated by the numerals land 2.

According to the preferred embodiment of' my invention a novel connection means is afforded, better shown in Figure 3, comprising a conveyery trough 3 having rounded edges 4 affording greater strength than by the old methodof attaching reinforcement members. The ends of each adjacent trough are reinforced by a gusset plate 7 constructed of a metal having a greater tensile streng-th than the troughs to permit the distribution of any undue stresses or loads over` a. wide area. This plate 7 isfurther secured on the end of each trough by a steel band 5 riveted to the side wallsof each trough. i c

LAt the endv of each 'trough' is riveted a steel band 6 across the bottom, which is also riveted to an angle 8, which angle isriveted` to the end of each trough and to a band 9 likewise riveted to each trough. Therev is also riveted to the upper track 10, bands 6 and 9 adapted to add strength to the connection. 'v 1"" A no vel means for fixing the lconnections by rivets is afforded having reference to Figure 13V. A hole is' countersunk inthe band 12. An ordinary hole vis bored inthe gusset plate 7 and the peripheral edge pressed around this hole so as to t in the countersinking of the hole in the band 12. *In alike manner holes are formed in the metal trough 11 and pressed to fit into the countersinking of the gusset plate 7. In the common aperture of the trough, the gusset plate and the band is secured by a rivet which, it will be seen, has a much greater purchase on the metal trough 11 than by the old method, as shown in Figure 14. Also the metal trough is given astrong purchase on the depressed section ofthegusset plate 7 andthe metal of the gusset plate 7 is in turn given a grip on the band 12. Y

An improved bolt 13, as shown in Figure 11, is adapted to serve as a connecting member for the adjacent conveyer troughs. Heretofore it has been necessary for the Workman performing the operation tohold the head 13 of the bolt from turning with a wrench while nuts on-'the bolts were tightened, one against Vthe other. In the improved bolt the shoulder 14 is provided adapted to iit in a recess 15 in the bands 5 andV 6, shown in Figure 3, thus preventing the bolt from turning and permitting thel operator use of both hands allowing'him to obtain a greater speed. The holes'16 are tapered VasY 'are the bolts 13, allowing a greater facility inl theinsertion of the bolts, as seen at 17 in Figures 2 and 12. A longer taper 18 is put on the end of the `bolt,as shownA in Figure 11, thus allowing greater rapidity and facility in inserting the bolt 13, even though the holes in the adjacent band do not match closely.

The conveyer is adapted to roll backand forth on the rollers`19 connected by 'axle 20, resting 'on and .rolling back and forth on an angle iron track'V 21, Vwith flanges 22 pressed outside the wheels as shownin the cross sec'- tionalview Figure 3.V Dirt or foreign matterhas been wont to ycollect between the roll-V ers 19 and prevented from falling away by the flanges 22, causing friction and great power loss.

This construction has been improved by placing the ianges 22 inside the rollers 19 as shown in Figures `7,8 and 9'. A4By this construction afconsiderable-'quantity of dirt ,or foreignv matter'may Aaccumulate underneath the conveyer before' retarding the action of the-rollers, as it is prevented from reaching that part of the mechanism by the flanges 22. In the event of the refuse eventually piling upto such a height that it flows overthe flanges 22, thereby interfering with the op.-l eration of the rollers 19, it may readily fall away from the angle track 21. j The -endsof the bands 5 and .6 adjoining the adjacent troughs are provided with inclined. upturne'd ends, as shown at 25, thus permitting the c'onnectingfears of the plates 5y and .6 to be drawn tightly together vby bolts13, even though the'adjacent troughsldo notliein the same horizontal'plane. In this manner vertical extension'of the troughsis provided and an open space at the point 24 made by the old type of connectionis done away with.

There is accomplished by this invention. an improved conveyer trough mechanism having a strengthened connector element allowing rapid assembly or dismantling and so constructed as to allow relative vertical movement between the adjacent troughs. An improved tracl is provided adapted to protect the conveyer mechanism from the deposition of any foreign material apt to retard the efficiency of operation. The convveyer trough has further been improved by the provision of a reinforcement on the edges integral with the trough.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not @Online myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding, the scope of the appended claims.

I claim:

l. A connection for conveyer troughs comprising a plurality of bands attached to the troughs one band being attached Aflush with l the end of one trough and the other band back from the end of the adjacent trough to allow overlapping thereof, the sides of the bands being formed to .provide frusto conical apertures to receive bolts, the bolts having longitudinally extending feathers adapted to lit in the open portions of the bands on the periphcries of the apertures to prevent rotative movement of the bolts with respect thereto,v

the adjacent edges of the bands being cut away to allow relative pivotal movement between the troughs.

2. A connection for conveyer troughs comprising registering eyelets provided on the sides of the troughs adjacent the ends, the

i Veyelets being formed to allow pivotal move-Y ment with respect to each other and provided with longitudinal slots, and bolts having tapered ends and longitudinal feathers fitted-in the eyelets, the tapered ends of the bolts being U adapted Vto facilitate insertion thereof, and

the feathers being adapted to fit in the slots in the eyeletsV to prevent rotation of the bolts with respect thereto.

In testimony whereof I affix my signature.
